Description
~2;;~109 BACKGROUN~ OF THE INVENTION
The present invention relates to a hinge with lifting-out protection, particularly for turnable and releasable connection of side walls of commercial vehicles with a chassis~
Hinges of the above-mentioned general type are known in the art and they must satisfy an important re~uirement that the respective side wall in raised condition must be secured against an unauthorized lifting-out. This is important especially when the respective commercial vehicle is used in a tlansi traffic with sealed storage space, wherein changes of the stored products must be preventéd. Furthermore, such hinges must provide for a safe handling, particularly during hanging-in and lifting-out of the side walls.
A two-part hinge is disclosed, for example, in the DE-GM 8,222,340. In this hinge a lower hinge part mounte~ on the vehicle forms an upwardly open bearing shell which is open in two axial direction and receives a pivot axle which is held at both sides in side walls ofan u~ hinge part. The side walls of the upper part form therefore a protection against axial displacement of the upper part of the hinge. The bearing shell o~ the lower part has in its central region a vertical slot which extends from the front portion of the same with the same width over the lower and up to the rear portion. ~his slot ¦
serves in hung-in position of the side wall in cooperation with a d sc mounted on the p vot axle, for protecting ~gsinst an ~2Z2109 1 unauthorized lifting-out of the side wall. For li~ting-out of the side wall, it must be turned downwardly by 180 and subsequently raised from the bearing shell. This raising is possible, since in this po~ition of the side wall, the disc because of its one sided hexagonal flattening, is disengaged from the slot. The lifting-out of a side wall is therefore characterized in the known hinge by two movements, namely the downward turning of the side wall and the sllbsequent raising-out from the bearing shell. This is disadvantageous since the downwardly turned side wall can be uncontrollably lifted from the bearing shell and dropped. This can take place, for example~, during maneuvering of the vehicle when the downwardly turned side wall runs on a re~istance.
Similar disadvantages are characteristic for the hinge disclosed in the DE-GM 7,501,762. In this hinge two bearing blocks formed of a sheet metal are mounted on a vehicle chassis with a lateral distance from one another and each form respectively an upwardly open bearing shell. A bearing pin welded on a bracket deformed from a sheet metal i5 in-serted with projectionsextending beyond the bracket into these bearing shells. Each projection has at its one side a flattening which in cooperation with the contour of the bearing recess of the abovementioned bearing blocks prevents lif~ng-out of the res~ective side wall in raised condition. However, it allows an uncontrollable li~ting-out in the turned-down 1 condition ~ The German Patent 2,748,185 shows a two-part hinge whose lower part is mounted on a vehicle and whose upper part is mounted on the respective side wall. The lower part has an upwardly open bearing shell which is closed in an axial direc-tion at its one end and receives a pivot pin mounted on the upper part and defininy the pivot axle of the hinge. An axle is further provided in the lower part at the closed side of the bearing shell in alignment with the pivot axle. This further axle is engaged in the turned upwardly condition of the side wall with a hook mounted on the upper part. A block arranged on the upper part and carrying the pivot pin, and this hook, together prevent an axial displacement of the side wall, whereas lifting of the latter in the turned upwardly condition is prevented by the hook engaging the abovementioned further axle on the lower part. The disadvantage of this hinge is that during the downward turning of the side wall even over a rela-tively small turning angle, the hook no longer engages with the axle and from this position an inadvertent lifting-out of the side wall is possible.
A ~iftable-out door hinge is disclosed in the D~-OS 2,628,951 , particularly for power vehicles,which has a vertical hinge axle. An upper branch part carries a spherical hinge pin which defines the hinge axle and engages in a cup-shaped recess in a lower branch part. A lifting-out protection is formed by a radially projecing safety blade provided in the 1 upper branch part and engaging in a slot recess in the other hinge blade. The safety blade is concentric with the hinge pin but surrounds the latter only partially. This hinge possesses the disadvantage in that the door plate can be lifted out in an outriyht manner, as soon as the safety blade leaves the slot recess.
~22Z109 SUMMARY ~F THE I~VENTION
Accordingly, it is an object of the present invention to provide a hinge for lifting-out protection which avoids the disadvantages of the prior art.
More particularly, it is an object of the present invention to provide a hinge with lifting-out protection which provides a sufficient protection from an unauthorized lifting-out of an upwardly turned side wall and at the same time guarantees a simple and safety handling.
In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated, in a hinge which additional-ly has a second pivot pin provided on a first hinge part and having a horizontal longitudinal axis, an opening and an upward-ly open shell provided on a second hinge part and extending in an axial direction of both pivot pins, wherein in a first axial end position of the first part the first pivot pin is located in the opening and the first hinge part is fixed in an axially positive manner relative to the second hinge part in its turning angle secured from lift-ing out, and in a second axial end position of the first hinge part, the second pivot pin is located in the shell and the first pivot pin is located outside of the opening.
When the hinge is designed in accordance with the ~5 present in~ention, a reliable all-sided fixation of the side ~222~)9 l wall is obtained, and the arrangement of the first pivot pin in the opening particularly counteracts an unauthorized vertical lifting of the upwardly turned side wall. Non-allowable mani-pulations with the hinge are easily recognizable by the custom employees. An axial arresting of the side wall relative to the longitudinal axes of the pivot pins takas place in its upwardly turned position and in a selectable turning angular region downwardly of for example of 145. Beyond this turning annular regiondbwnwardly the side wall can be axially displaced in a further angular region depending upon the respective vehicle type, until the first pivot pin leaves the opening and the second pivot pin is displaced into the shell. Only after this is it possible to lift the side wall from the shell upwardly. With the axial displacement in the movement sequence for lifting out of the side wall with two-stage rectangular chanqe of the movement direction, a "bafflel' is built which excludes the unintentional dangerous lifting-out of the side wall with a very high probability. The parts of the hinge can be forged or cast for high strength and robust construction, and connected with a side wall or a vehicle chassis by screwing, riveting or welding.
In accordance with another feature of the present invention, the longitudinal axes of the pivot pins are arranged in alignment with one another. With the aligned arrangement ~f the pivot pins the geometry o the first hin~e part mounted ~222~09 1 on the si~e wall of the vehicle is simplified, and moreover, the advantage is provided in that during turning of the side wall and relieviny its axial arresting, in each angular position the upwardly open shell of the second hinge part of the hinge stands opposite the second pivot pin, so that in all angular positions this shell can perform its holding function in a simple manner.
Still another feature of the present invention is that the axially positive fixing of the first hinge part relative to the second hinge part is performed by a collar in~
serted in a recess of the second hinge par~. This provides for relative axial fixing of the part of the hinge in the selected turning angular region of the side wall in a si~iple manner. By varying the length of the circumference o~ the collar, the turning angular region can be fixed in any way, and after its exceeding an axial displacement possibility of the side wall is obtained.
A further feature of the present invention is that the collar is arranged in the connecting region of the pivot pin .
This provides for an especially structurally favorable hinge.
Still a further feature of the present invention is ~hat a web is form~donto the connecting region of the pivot pin and connects the pivot pins with a base plate of the first hinge part. In accordance with this feature a material-saving construction of the first hinge part with a high strength i3 1 provided.
An additional feature of the present invention is that the web has a limiting surface facing toward the second pivot pin, and the collar also has a limiting surface facing toward the second pivot pin, wherein these limiting surfaces lie in a common plane extending normal to the longitudinal axes of the pivot pins. This construction provides for the advantage in that the web, as considered in axial direction forms addi-tionally to the collar, an abutting surface for the first part op~osite to the upwardly open shell during axial displacement.
Yet an additional feature of the present invention is that the width of the web in direction of the longitudinal axes of the pivot pins substantially corresponds to the distance of a shell-facing limiting surface of the recess from the opening which receives the first pivot pin. In this case the web simultaneously forms an abutment surface for the first part of the hinge during its movement in direction to the opening which receives the first pivot pin. The first hinge part is here fixed axially at both sides, when the collar is located ~0 in the recess.
Finally, still another feature of the present inventio n is that the distance between limiting surfaces of the shell and a block which defines the opening, both extending normal to the longitudinal axes of the pivot pins and facing each other, is smaller than the distance between the free ends of the pivot pins and is greater than the

The side walls of the upper part form therefore a protection against axial displacement of the upper part of the hinge. The bearing shell o~ the lower part has in its central region a vertical slot which extends from the front portion of the same with the same width over the lower and up to the rear portion. ~his slot ¦
serves in hung-in position of the side wall in cooperation with a d sc mounted on the p vot axle, for protecting ~gsinst an ~2Z2109 1 unauthorized lifting-out of the side wall.

An axle is further provided in the lower part at the closed side of the bearing shell in alignment with the pivot axle. This further axle is engaged in the turned upwardly condition of the side wall with a hook mounted on the upper part. A block arranged on the upper part and carrying the pivot pin, and this hook, together prevent an axial displacement of the side wall, whereas lifting of the latter in the turned upwardly condition is prevented by the hook engaging the abovementioned further axle on the lower part. The disadvantage of this hinge is that during the downward turning of the side wall even over a rela-tively small turning angle, the hook no longer engages with the axle and from this position an inadvertent lifting-out of the side wall is possible.
A ~iftable-out door hinge is disclosed in the D~-OS 2,628,951 , particularly for power vehicles,which has a vertical hinge axle. An upper branch part carries a spherical hinge pin which defines the hinge axle and engages in a cup-shaped recess in a lower branch part. A lifting-out protection is formed by a radially projecing safety blade provided in the 1 upper branch part and engaging in a slot recess in the other hinge blade. The safety blade is concentric with the hinge pin but surrounds the latter only partially.

Accordingly, it is an object of the present invention to provide a hinge for lifting-out protection which avoids the disadvantages of the prior art.
More particularly, it is an object of the present invention to provide a hinge with lifting-out protection which provides a sufficient protection from an unauthorized lifting-out of an upwardly turned side wall and at the same time guarantees a simple and safety handling.

When the hinge is designed in accordance with the ~5 present in~ention, a reliable all-sided fixation of the side ~222~)9 l wall is obtained, and the arrangement of the first pivot pin in the opening particularly counteracts an unauthorized vertical lifting of the upwardly turned side wall. Non-allowable mani-pulations with the hinge are easily recognizable by the custom employees. An axial arresting of the side wall relative to the longitudinal axes of the pivot pins takas place in its upwardly turned position and in a selectable turning angular region downwardly of for example of 145. Beyond this turning annular regiondbwnwardly the side wall can be axially displaced in a further angular region depending upon the respective vehicle type, until the first pivot pin leaves the opening and the second pivot pin is displaced into the shell. Only after this is it possible to lift the side wall from the shell upwardly. With the axial displacement in the movement sequence for lifting out of the side wall with two-stage rectangular chanqe of the movement direction, a "bafflel' is built which excludes the unintentional dangerous lifting-out of the side wall with a very high probability. The parts of the hinge can be forged or cast for high strength and robust construction, and connected with a side wall or a vehicle chassis by screwing, riveting or welding.
In accordance with another feature of the present invention, the longitudinal axes of the pivot pins are arranged in alignment with one another. With the aligned arrangement ~f the pivot pins the geometry o the first hin~e part mounted ~222~09 1 on the si~e wall of the vehicle is simplified, and moreover, the advantage is provided in that during turning of the side wall and relieviny its axial arresting, in each angular position the upwardly open shell of the second hinge part of the hinge stands opposite the second pivot pin, so that in all angular positions this shell can perform its holding function in a simple manner.

serted in a recess of the second hinge par~. This provides for relative axial fixing of the part of the hinge in the selected turning angular region of the side wall in a si~iple manner. By varying the length of the circumference o~ the collar, the turning angular region can be fixed in any way, and after its exceeding an axial displacement possibility of the side wall is obtained.
A further feature of the present invention is that the collar is arranged in the connecting region of the pivot pin .
This provides for an especially structurally favorable hinge.
Still a further feature of the present invention is ~hat a web is form~donto the connecting region of the pivot pin and connects the pivot pins with a base plate of the first hinge part. In accordance with this feature a material-saving construction of the first hinge part with a high strength i3 1 provided.
An additional feature of the present invention is that the web has a limiting surface facing toward the second pivot pin, and the collar also has a limiting surface facing toward the second pivot pin, wherein these limiting surfaces lie in a common plane extending normal to the longitudinal axes of the pivot pins. This construction provides for the advantage in that the web, as considered in axial direction forms addi-tionally to the collar, an abutting surface for the first part op~osite to the upwardly open shell during axial displacement.
Yet an additional feature of the present invention is that the width of the web in direction of the longitudinal axes of the pivot pins substantially corresponds to the distance of a shell-facing limiting surface of the recess from the opening which receives the first pivot pin. In this case the web simultaneously forms an abutment surface for the first part of the hinge during its movement in direction to the opening which receives the first pivot pin. The first hinge part is here fixed axially at both sides, when the collar is located ~0 in the recess.
Finally, still another feature of the present inventio n is that the distance between limiting surfaces of the shell and a block which defines the opening, both extending normal to the longitudinal axes of the pivot pins and facing each other, is smaller than the distance between the free ends of the pivot pins and is greater than the
2~109 1 distance between the shell-facing lateral limiting surface of the collar and the free end of the opening-faced first pi~ot pin.
In this construction it is guaranteed that during axial dis-placement of the first hinge part and thereby the side wall S relative to the second hinge part, a downward falling of the side wall is excluded. At the same time the first pivot pin cooperating with the opening can be completely withdrawn from the opening. After the predetermined turning angular region and the lateral displacement, the side wall is finally carried only by the shell so that a subsequent lifting of the side wall in an upward direction is possible.
The novel features which are considered as charac-teristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with addi-tional objects and advantages thereof, will be best understood from the following description ofaspecific embodiment when read in connection with the accompanying drawings.

lZ2;~109 DESCRIPTI~N OF A PREFERRED EMBODIMENT
FIG. 1 shows a side wall which is identified with reference numeral 1 and connected with a chassis 3 of a com-mercial vehicle, for example a truck by a hinge 2.
The hinge 2 has a first hinge part 4 mounted on the side wall 1 and having a first pivot pin 5 and a second pivot pin 6. It also has a second hinge part 7 mounted on the chassis
3 and having a block 8 with an op~ning 9, and a shell 10 spaced from the block 8 at a distance and open upwardly. The mounting of the hinge parts 4 and 7 of the hinge 2 on the side wall 1 and the chassis 3, respectively can be performed by welding, screwing or riveting ,that is not shown in the drawing.
The pivot pins 5 and 6, as well as the opening 9 and the open shell 10 are in alignment with one another. Both hinge parts 4 and 7 of the hinge 2, are for example drop-forged pieces. The hinge part 7 can be particularly formed also as steel cast piece.
The hinge part 4 of the hinge 2, in the raised posi-tion of the side wall 1 of FIG. 1, is secured against lifting-out in direction of the arrow 11 by the pivot pin 5 located in the opening 9. Arresting of the hinge part 4 in an axial direction, or in other words in direction of the arrow 12 is performed by a collar 13 of the first hinge part 4.
The collar 13 is arranged coaxially to the pivot pins 5 and 6 along a part of the circumference. It can be brought -12~
12Z2~9 1 in engagement with a recess 14 of the second hinge part 7 and provides then,with a lateral limiting surface 18 abutting against a lateral limiting surface 19 of the recess 14,for the abovementioned axial arresting.
A web 15 carries the pivot pins 5 and 6 and is con-nected with a base plate 16. The first hinge part4is mounted via the base plate 16 on the side wall 1.
The length of the pivot pins 5 and 6 is dimensioned so that in the raised condition of the side wall 1 it is h~ only by the first pivot pin 5 located in the opening 9, whereas in this axial position the second pi~ot pin 6dbesnot have any function.
FIGS. 2 - 6 show the hinge in positions in which the side wall 1 is turned downwardly. It can be seen that the collar 13 which in the raised position of the side wall 1 and in the turning angular region extening from it downwardly over for example 145 provides in cooperation with the recess 14 an axial arresting, allows under this turning region an axial dis-placement in direction of the arrow 12, shown in FIG. 1 . For . this purpose the collar 13 is shaped so that its outer limit extending along the circumference forms a circular line with a : rectilinear limiting line which in the turned down condition of the first hin~e part 4 extends parallel to a mounting plate 17 of the seccnd hinge part 7. Itoan ~ther be seen that the collar 1.3 which abuts with its limiting surface 18 against the limiting suxface 19 located away from the opening 9, determines by its 12~;2109 l peripheral extension such a turning angular region of the hinge part 4 over which an axial displacement in direction of the arrow 12 is not possible.
The web 15 is dimensioned in its width extending in axial d.irection or in other words in direction of the arrow 12, so that this width substantially corresponds to the distance between the limitin~ surface 19 of the resess 14 and the op-posite lateral limiting surface 20 of the block 8. Because of these features, the side wall 1 is axially arrested at both sides during the engagement of the collar 13 in the recess 14.
The collar 13 is shaped on theweb 15 so that in the web its limiting surface 21 which faces toward the second pivot pin 6 and extends normally to the longitudinal axes of the pivot pins 5 and 6 lies in one plane with the lateral limiting surface 18 of the collar 13. Because of this an active abutment surface during axial displacement of the first hinge member 4 in direction of the arrow 12 relative to a lateral limiting surface 22 of the shell 10 is increased.
FIGS. 3 - 6 show the hinge 2 in a turned down posit-on in which in addition, the side wall 1 is displaced laterally so tha~ the first pivot pin 5 is completely withdra~l from the opening 9 and the second pivot pin 6 lies in the shell 10. Onl~7 in this position there is a possibility that the side wall 1 can be lifted upwardly out of the shell 10. It is clear that especially with a vehicle standing in an inclined position, g 1 a protection from aninadvertent l~fting-out of the side wa~ 1 is provided, since the collar 13 and the web 15 in cooperation with the shell 10 limits a lateral axial displacing movement of the side wall 1 in any case.
It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the type described above.
While the invention has been illustrated and described lG as embodied in a hinge with liftiny-out protection, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
~ithout further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpcint of prior art, fairly constitute essential characteristics of the generic or s~ecific aspects of this invention.
~hat is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.
The pivot pins 5 and 6, as well as the opening 9 and the open shell 10 are in alignment with one another. Both hinge parts 4 and 7 of the hinge 2, are for example drop-forged pieces. The hinge part 7 can be particularly formed also as steel cast piece.
The hinge part 4 of the hinge 2, in the raised posi-tion of the side wall 1 of FIG. 1, is secured against lifting-out in direction of the arrow 11 by the pivot pin 5 located in the opening 9. Arresting of the hinge part 4 in an axial direction, or in other words in direction of the arrow 12 is performed by a collar 13 of the first hinge part 4.
The collar 13 is arranged coaxially to the pivot pins 5 and 6 along a part of the circumference. It can be brought -12~
12Z2~9 1 in engagement with a recess 14 of the second hinge part 7 and provides then,with a lateral limiting surface 18 abutting against a lateral limiting surface 19 of the recess 14,for the abovementioned axial arresting.
A web 15 carries the pivot pins 5 and 6 and is con-nected with a base plate 16. The first hinge part4is mounted via the base plate 16 on the side wall 1.
The length of the pivot pins 5 and 6 is dimensioned so that in the raised condition of the side wall 1 it is h~ only by the first pivot pin 5 located in the opening 9, whereas in this axial position the second pi~ot pin 6dbesnot have any function.
FIGS. 2 - 6 show the hinge in positions in which the side wall 1 is turned downwardly. It can be seen that the collar 13 which in the raised position of the side wall 1 and in the turning angular region extening from it downwardly over for example 145 provides in cooperation with the recess 14 an axial arresting, allows under this turning region an axial dis-placement in direction of the arrow 12, shown in FIG. 1 . For . this purpose the collar 13 is shaped so that its outer limit extending along the circumference forms a circular line with a : rectilinear limiting line which in the turned down condition of the first hin~e part 4 extends parallel to a mounting plate 17 of the seccnd hinge part 7. Itoan ~ther be seen that the collar 1.3 which abuts with its limiting surface 18 against the limiting suxface 19 located away from the opening 9, determines by its 12~;2109 l peripheral extension such a turning angular region of the hinge part 4 over which an axial displacement in direction of the arrow 12 is not possible.
The web 15 is dimensioned in its width extending in axial d.irection or in other words in direction of the arrow 12, so that this width substantially corresponds to the distance between the limitin~ surface 19 of the resess 14 and the op-posite lateral limiting surface 20 of the block 8. Because of these features, the side wall 1 is axially arrested at both sides during the engagement of the collar 13 in the recess 14.
The collar 13 is shaped on theweb 15 so that in the web its limiting surface 21 which faces toward the second pivot pin 6 and extends normally to the longitudinal axes of the pivot pins 5 and 6 lies in one plane with the lateral limiting surface 18 of the collar 13. Because of this an active abutment surface during axial displacement of the first hinge member 4 in direction of the arrow 12 relative to a lateral limiting surface 22 of the shell 10 is increased.
FIGS. 3 - 6 show the hinge 2 in a turned down posit-on in which in addition, the side wall 1 is displaced laterally so tha~ the first pivot pin 5 is completely withdra~l from the opening 9 and the second pivot pin 6 lies in the shell 10. Onl~7 in this position there is a possibility that the side wall 1 can be lifted upwardly out of the shell 10. It is clear that especially with a vehicle standing in an inclined position, g 1 a protection from aninadvertent l~fting-out of the side wa~ 1 is provided, since the collar 13 and the web 15 in cooperation with the shell 10 limits a lateral axial displacing movement of the side wall 1 in any case.
